Question

Differentiate between Conduction, Convection and Radiation.

Answer 1

Conduction	Convection	Radiation
Conduction takes place in solids	Convection takes palace in liquids and gases.	All hot objects give away heat by radiation
Heat transfer takes place on contact between hot to cold molecule.	The hot molecules goes away from the heat source to the coldest region to the top.	Heat is carried as small packets of energy, Which travel in straight line.
Conduction does not  occur in vacuum.	Convection does not occur in vacuum.	Radiation can occur in vacuum.
Heat transfer can occur in any direction from hot to cold body.	Heat transfer occur along the path of convection current from heat source to the coldest region on the top.	Heat transfer occurs when photons are met with an obstacle.
Conduction is a relatively slow process.	This process is faster than conduction, but slower than radiation	Radiation is fastest way of heat transfer.
